1论文题目：6.0Mt/a炼焦煤选煤厂初步设计专业：矿物加工工程学生：陈家军（签名）________指导老师：杨志远（签名）________摘要本设计的主要任务是完成年产量600万吨炼焦煤选煤厂的初步设计，通过对原煤的资料分析，可以根据综合资料画出可选性曲线，从其上可知其选别的难易程度以及选别的最佳工艺流程，另外分析比较知采用不分级入洗，最后确定采用三产品重介旋流器+浮选的工艺流程，计算出数质量、确定设备选型、完成了生产辅助设施、场地总平面和劳动定员设计等，绘制了工艺流程、设备关联、厂房布置图。本设计的特点是采用了无压三产品重介旋流器，其处理里量大，这种旋流器实现了选煤厂的整体化，大型化，经济实用性强且是处理难选煤，高灰粉煤的有效分选设备；浮选采用的是浮选机，处理0.5mm以下的细粒煤，达到选厂的要求，基本的要求是充分考虑环境问题，选煤厂用水采用闭路循环，大大减少了水对环境的污染，节约了水自然，达到了经济节能环保的生产理念。关键字：6.0Mt/a，炼焦煤选煤厂，工艺，初步设计2Sbuject:PrimaryDesignofCokingCoalPreparationPlantwithCapacityof6.0Mt/aSpecialty:MineralProcessingEngineeringName:JiajunChen(Signature)___________Instrutor:ZhiyuanYang(Signature)___________ABSTRACTThemaintaskofthedesignofthepreliminarydesignofthecompletionoftheannualproductionof600tonesofcokingcoalpreparationplantInformatingontherawcoalanalysis,Comprehensiveinformationtodrawthewashabilitycurves,wecanseefromitselectiontoanotherlevelofdifficultyaswellasselectedotherbestprocess,Comprehensiveinformationtodrawthewashabilitycurves,wecanseefromitselectiontoanotherlevelofdifficultyaswellasselectedotherbestprocess.Thecharacteristicsofthisdesignistheuseofanon-pressureproductdensemediumcyclonewherelargeamountofitsprocessing,thiscyclonetoachievethecoalpreparationplantandlarge-scale,economicpracticability,anddealingwithdifficultCoalofhighashandpulverizedcoalsortingequipment;Flotationisusedintheflotationmachineprocessing0.5mmthefinecoaltoachievetherequirementsoftheprocessingplant,thebasicrequirementistogivefullconsiderationtoenvironmentalissues,Coalpreparationplantwaterclosedloop,greatlyreducingthewaterpollutionoftheenvironment,savingthewaternaturally,andtotheeconomicproductionofenergysavingandenvironmentalprotectionconcept.KEYWORDS:6.0M/t,cokingcoalpreparation,crafts,preliminarydesign3目录前言................................................................................................................................11设计概要......................................................................................................................21.1项目背景...............................................................................................................21.2可行性研究概要...................................................................................................21.3供水、供电...........................................................................................................21.4产品品种和用途....................................................................................................31.5设计规模及工作制度............................................................................................32原煤资料及计算...........................................................................................................42.1原煤概况................................................................................................................42.2煤质特征................................................................................................................42.3煤的可选性..........................................................................................................42.3.1煤质资料依据.................................................................................................42.3.2可选性曲线................................................................................................133选煤工艺方法的确定.................................................................................................163.1选煤方法..............................................................................................................163.2入选方式-混合与分组、分级问题.....................................................................173.2.1分组讨论.......................................................................................................173.2.2分级讨论.......................................................................................................173.3选煤方法的确定..................................................................................................183.3.1跳汰分选指标的计算...................................................................................183.3.2重介（三产品）分选指标计算...................................................................233.3.3选定工艺流程的介绍...................................................................................273.3.4工艺流程图...................................................................................................293.4工艺流程的计算..................................................................................................303.4.1准备作业的计算...........................................................................................303.4.2分选作业的计算...........................................................................................314设备选型及计算.........................................................................................................524.1选型与计算的原则和规定.................................................................................524.2主要设备选型及计算..........................................................................................535工艺布置.................................................................
